Some patients who do not respond to therapies for depression may simply have received inadequate treatment, having, for example, been prescribed a drug at a dosage too low to be effective or having been taken off a drug too soon.

原句即为正确选项

问题来了..

白勇语法书提了好几次，现在完成时不得做分词修饰

跟这题的答案有很大的冲突

请问那位r 可以解释一下

那些对depression治疗没有response的病人很容易得到不充分的治疗，比如，被开的处方药剂量太小不足以有效或者被停药太早。

这样看起来，having been done是谓语伴随状语，逻辑主语是patient，而不是作定语修饰treatment（个人意见）

重看了一遍白勇~

是说:~ing分词的完成时态不能作名词的定语,必须转化为定语从句.但没说不能作伴随状语.

这题having...是不是做do not respond的伴随状语？

请NN指正~
